Roof Top Waterproofing
Why Roof Waterproofing is Critical
Your roof is the first line of defense against Singapore's weather:
- Monsoon Seasons: Heavy rainfall from November to January and June to September
- UV Exposure: Intense equatorial sun degrades waterproofing materials
- Temperature Fluctuations: Daily variations causing expansion and contraction
- Ponding Water: Flat roofs prone to water accumulation
Common Roof Problems
-
Membrane Failure
- Blistering and cracking
- Seam separation
- UV degradation
- Punctures from foot traffic
-
Structural Issues
- Cracks in concrete roof slabs
- Failed expansion joints
- Deteriorating flashings
- Blocked drainage systems
-
Age-Related Deterioration
- Loss of flexibility
- Surface erosion
- Chemical breakdown
- Root penetration

- Water stains on ceiling below
- Efflorescence (white deposits)
- Spalling concrete
- Oil-stained areas with water penetration
Structural Concerns
- Settlement cracks at walls
- Joint separation
- Inadequate slope for drainage
- Failed waterproofing at edges
